About the B-Vac Black Vacuum Seal Bags (120 Microns)
B-Vac black bags
Made for food that has to look good
Most vacuum bags are clear because clear is practical. B-Vac black vacuum seal bags exist for presentation: smoked fish, cured meat, premium cuts and artisan products get a cleaner, retail-ready finish, with a smooth clear side to see and label the contents.

Clear bag or black bag?
Clear vacuum bag
Functional storage
Practical when the goal is protection, freezer storage and simple visibility.
B-Vac black bag

Smoked fish
A clean, premium pack for display or gifting.
Cured meats

The film
120 microns, structure on the black side
- 01
Structured black side
Draws the air out fast for a clean, reliable seal.
- 02
Light protection
Blocks light to one face, for products that fade or degrade under light.
- 03
Food-safe film
PE/PA multilayer: plasticiser-free, BPA-free, tasteless and odourless.
B-Vac is thicker than the 90-micron R-Vac, rated for years in the fridge and freezer and suitable for sous vide. The black side blocks light to that face only; for full light protection on both sides, choose the metallised K-Vac bags.
Machines
External and chamber sealers
B-Vac seals on LAVA vacuum sealers, on other external sealers that take structured bags, and on chamber machines, which makes it useful for commercial kitchens and producers. With a non-LAVA machine, check that it seals 120-micron structured film.
Which LAVA bag for which job
| Bag | Thickness | For |
|---|---|---|
| R-Vac | 90µm | The clear everyday bag |
| B-Vac | 120µm | Presentation, black finish, light on one side |
| RS-Vac | 160µm | Bones and sharp edges |
For puncture resistance on bone-in cuts, step up to the RS-Vac heavy-duty bags. To cut your own lengths in the same black film, see the B-Vac black rolls.

04 · FAQ
Common questions
What is the difference between the B-Vac and a standard clear R-Vac?
Two things. The B-Vac has a black structured side for presentation and light protection, and it is thicker at 120 micron versus the R-Vac’s 90 micron. The R-Vac is the clear everyday bag; the B-Vac is for when the pack needs to look premium or the contents need shielding from light.
Do these block light completely?
The black side blocks light to that face of the pack. The transparent side still lets light through and lets you see the contents. For full light blocking on both faces, a fully metallised bag like the K-Vac is the better option. The B-Vac is a presentation bag first, with partial light protection as a bonus.
Will the B-Vac seal on my machine?
Yes. It works on LAVA vacuum sealers, other external sealers, and chamber machines. The structured black side draws air out the same way a standard structured bag does. If you use a non-LAVA machine, confirm it handles 120-micron structured film.
What is the difference between clear/black and black/black?
Clear/black has one transparent side and one black side, so you can see the contents through the clear face. Black/black is black on both sides for a fully opaque pack. Choose clear/black if you want visibility, black/black for maximum presentation or light protection.
Can I use these for sous vide?
Yes. The B-Vac is food safe and suitable for sous vide. For extended high-temperature cooks, check the temperature guidance as you would with any bag.
Do you make custom sizes?
Yes. We can produce any size of B-Vac from 3,000 units. Contact us with your specification.
